This invention relates to improvements in stretchbeardsfor drawingpaper. i f Heretoit'pre it has been the practice ofart; ists when preparing a sheet of drawing paper for attachment to a drawing board,,to wet both sides of the sheet and th n blot the same about one orone and onerhalf inches from. the edges thereof. Glue is then applied on the. underside of the blotted area and the sheet placed down upon a drawing board but during the drying of the lue, the artist must pull the paper from all sic es to tightly stretch the same before the glue has entirelyhardened. This is a very longand tedious, operation, and frequently the pull is not sufficient to, successfully stretch the "paper to thesatisfaction of the artist, in which instances thumb tacks are resorted to. Of course drawing paper may be purchased in a stretched posi-v tion upon a board,but this is very costly. It is therefore-the aim ofmy invention to overcome these objections by providing a draw-. ing board by which one unfamiliar in the are may quickly mount or demount a sheet of drawing paper upon a board and when mounted thereon, the'sheetwill be tightly held in a stretched condition. j l

Anotherobject of the invention resides in a s r t h 'b'ee f wing- Pap in, w v the side edges of the paper are held by re movable clamping strips, and the strips in turn secured to, the board proper by spring clips which in no wayinterterewith the free movement of the hand during drawing upon the paper, nor with the sliding movement of the T square should one be usediin connection with the work.

With these and other objects in view, the invention resides in the certain novel construction, combination and arrangement of parts, the essential features of which are ereinafter fully described, are particularly pointed out in the appended claims, and are illustrated'in the accompanying drawing, in which:

Figure'l is a perspective view of. my improved stretcher board showing one of the clamping; members in separated position fromtheb'oard. V

e e ring to, the. drawing constructedof three pieces of flat rectangular material, the 19W ermOst piece 1 being desig l sides of the intermediate piece 12, in order to provide extendingflanges 14;. The uppermost-- piece 13 is of vertical sectional view on; the line by "ref ee, characters, the numeral 10 designates my im provedstretcher board in its entirety which is a size slightly greater 7 than the intermediate piece12, but consider ably smaller than the base piece 11 so that all of thesides of the uppermost piece 13 extend equal distances from all sides of the intermediate piece 12 in order to provide overhanging flanges 1 5. I f Th fl g sl ti t r ats or t e r ception ofthe several clamping strips or bars 16, the same being of a length short of. the length of the respective sidesof the board, as

till

best seen in Figure l of the drawing. 7 These clamping strips l6 are of a thickness to-fit between the overhanging flanges 15 and the flanges ltwith a thickness of paper clamped therebetween as shown in Figure 2, the said Pap ing de ig at d. y the r f en e ha acter A. The top recessed inwardly a edges s, 1 of U-shaped clamping elements or clips 18, the other legs of the clips engaging the under faces of the strip 16 are side of the lowermost plecerll V In practice, a sheet of drawing paper slightly larger in area thanfthe top surface of the board 10 is wet in the usual way and placed over the fiat top section1'3so that the edges of the edges o t e ec o 1 itil g u ert d tha ha l mpins'st s 1 a cl p J are from the outer longitudito receive the upper leg P per A, ex nd eyo -t the edges: of the board removed from the board. After the paper has been so positioned, one of the strips 16 is placed in position so that one edge of the strip underlies the overhanging edge 15 of the top section'13, whereupon one edge of the paper is' clamped between the strips 16. 15, against the sides I and beneath the flange I v of -the"intermediate' section 12-and against the upper side of the lowermost section 11.

The other clamping strips-16 are likewise aplied to the respective sides'ofthe' board so that all sides of the paper-glare: securely clamped and when so clamped, the paper assume's a tightly stretched position aorossthe upper flat face of the board. It will now be seen -that the paper is incondition toreceivev the work and there are no obstructions which might 'interfere with the free 'movement of the hands of the artist, In some cases itmay be necessary to employ a T-square-in connectio'nf fwith the work being performed and whichfinstrument may hie-freely slid along without interference the clamping clips 18 due to the fact that the upper legs-ofthe same arecountersunk in the top of the strips 16. 2

' 'When it is desired to remove the paper from the .board, it is only necessary to first remove the clamping clips 18 and then lift the several clamping st ips 16 from clamping engagementwith the'edges of the paper; now free to -be'sepa'rated from The paper is the board, after which the edges may be crimped up to remove the creased areas 1 sorted to if desired,

formed by the'clampin-g strips. c Although wood is preferably used in the construction of the board, it will be understood "that other material may be used if desired; Also,*the board maybe constructed of a single piece of material instead of the three pieces hown' in the drawing, 'but the flanges 14 and 15 must be formed'therein. *WhileI have shown and described whatI deem to be the most desirable'embodiment of my invention, I wish it to be understood that various changes in construction, may be renor to anything less vention limited only by the appended claims. what I claim'as new and desire to secure by Let; ters Patent is 1. -A stretcher board comprising a flat straightsided body, flanges extending from the sides of said 'body below. the top surface thereof, flanges extending from the sides of said body and overhanging 1-.he first =men-- ,tion'ed flanges,
